Blackstone determines the best oil brand
The good news is it looks like it's all of them :thumbup: . Now I don't feel so bad about being cheap and buying Castrol.
Blackstone's report: https://www.blackstone-labs.com/News...uly-1-2017.php Article highlighting findings: http://thegarage.jalopnik.com/why-ex...ney-1797241527 I'm sure guys who are putting in a bunch of track time will disagree, but for the rest of us this is useful. |
FAKE OIL TESTS!
|
So, is a 25% difference between the best and worst in terms of wear rate (based on their iron parts per million chart) really negligible?
|
I think their point is that 25% of negligible is negligible.

My thought there is either the oil is being changed sooner than it needs to be (which is very possible) or if this isn't a limiting factor in the life of the oil then it's not worth looking at/comparing. Unless it comes with big downsides elsewhere I have a hard time with just handwaving away 25% improvements. |

"Shell Rotella T6 had the lowest iron wear rate, at 2.03 ppm per 1,000 miles, while Royal Purple 5W/30 had the highest wear rate, at 2.58 ppm per 1,000 miles. The difference is just over half a part per million per 1,000 miles, which is almost completely negligible. In a typical engine, a half a part per million of the oil in the sump is such a small quantity that you wouldn’t be able to see it without a microscope." And "if you know it’s there, it might bother you, but realistically, you’ll never notice the difference." So try to think of it like: How much more are you willing to pay for 25% extra of nothing? |
I would have been more interested if they had published the change in viscosity of the different oils.

If you convert both of those to % of ppm the percentage improvement is actually 0.00000055% Which in essence is zero. |
Bubba could have told us that there is no difference, without a fancy study ....... but, nobody asked him .....:sigh:

Good thing I never fell for royal purple.

I was thinking in the context of taking the car to the track. I usually change my oil pretty frequently during track season, but I was curious how the different brands maintained their viscosity with age.

Plenty of old timers got 200K on cars with Dino oil and orange Fram filters. Guess this backs them up.
Pick a good oil -stop worrying what others are using - spend 20 bucks to test it - have piece of mind and go enjoy the car. I love the arguments at the PPM level - too funny. |
